[OpenAFS] Problems loading openafs kernel module on RHEL5 box

Setup:
RHEL-5.1, kernel 2.6.18-53.1.13.el5xen (same with kernel lacking xen =
support)
openafs kernel module is from =
kmod-openafs-xen-1.4.6-2.2.6.18_53.1.13.el5.i686.rpm
available from the openafs site.

Symptom: when performing a "modprobe openafs" the system log shows:
=3D=3D=3D
Found system call table at 0xc06024c0 (pattern scan)
Address 0xc06024c0 is not writable.
System call hooks will not be installed; proceeding anyway
=3D=3D=3D
According to older mailing list entries this is due to the Redhat =
kernels being built
with the CONFIG_DEBUG_RODATA=3D1.

Question: is there any way to avoid having to build a new kernel if one =
wants to run
OpenAfs on a RHEL5 or CENTOS5 box? Anyone found e.g. some kernel command =
line parameter
to disable the write protection of the system call table?

Or am I just overlooking something basic ?

Thanks for any hints,

	Uli
